We are the dark, we are the saints of blood at night
We hear the call when the moon shines red
We grab your body, in the morning all we are
Satisfied and you're dead

The song is by Powerwolf, but I prefer the accoustic cover version:

Inspired by a post (113757) by Antlers Anon and dedicated to all the hordes of Cain who create images on moonlit nights.
